Suppose that a developer has built an AI which predicts the day's closing price given the stock's history and current open price, and has also built a website around it, on which such predictions are provided for a fee. Are there any legal issues that may arise from selling these predictions? Are there any steps a developer and site operator would need to take to make this business model legal?
I know that there is something about becoming an RIA (Registered Investment Advisor) or something for non-opinionated stock price sharing, but I am not clear if this is needed or would cover this situation.
